MACHINE FOR UP SETTING CARRIAGE-IRONS.

SPECIFICATION forming part of Letters Patent No. 373,612, dated November 22, 1887.

" Application filed January 12, 1886. Serial Xo. 188,354. (No model.)

To all whom it may concern:

Be it known that I, FRANK ScHRnIDr, of Mansfield, county of Richland, and State of Ohio, have invented a new and useful Improvement in Machines and Dies for Upset ting Carriage-Irons, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to the means for regulating the quantity of stock to be upset or operated upon to form the joints or other enlargements in the bars used for the carriage'top bows and other irons,to the construction of the gripping-dies, and to the meansfor effecting the adjustment of said dies, and will be fully understood from the following description and claims.

In the accompanying drawings, Figure l is a plan view of an upsetting-machine embracing my improvements. Fig. 2 represents a vertical longitudinal section through the same; Fig. 3, a broken plan view, enlarged, showing the means for effecting the adjustment of the movable parts of the gripping-jaws. Fig. 4 shows a modification in the means for effecting the adjustment of the grippingjaws or dies. Figs. 5 to 16, inclusive, illustrate various forms of gripping-dies and dominos adapted for use 0 in connection with my improved machine. Figs. 17 to 20, inclusive, illustrate various forms ofirons operated upon by myimproved dies.

A indicates a strong upright frame and ta- 5 ble of iron or other suitable material upon and in suitable ways or hearings, in which the operative parts of the machine are mounted, A and A indicating stout transverse end bars or ribs thereof, for sustaining the end-thrust of 0 the dies, hereinafter described, and A and A" stout intermediate transverse bars on the frame, forming fixed supports for and provided with ways for the plunger operating the movable parts of the gripping-jaws and die. 5 The front end bar, A,is notched or recessed at or near the center of its length to permit the introduction of the bars to be operated upon and to allow the same to project, and the parts of the stationary gripping-jaw and die, here- ,50 inat'ter described, rest snugly against and are held in operative position by the inner vertical face, a, of said bar.

In suitable bearings, near the rear end of the frame, is mounted a stout transverse shaft,

B, provided with a suitable band and fly wheel, B, through which acontinuous rotary movement is imparted to the shaft in the direction indicated by the arrow, from any convenient source of power. The shaft B has a cam projection or rib,b,formed upon one side, 6.) through which motion is imparted to the movable parts of the gripping-dies or domino, in

a manner that will be explained.

O represents a stout block or cross-head adapted to slide in suitable ways on the table or top of the frame A, and provided at its rear end, adjacent to the shaft B, with a semi-eylindrical groove, 0, in which is fitted the forward end of a thrust-bar or stout rod, O, rounded or made semi-cylindrical in form at its front end to fit the groove'c and to pivot said end therein. The rear end of this rod or bar has a horizontal semi-cylindrical groove,

0, formed in it, matching and adapted to receive the rounded outer end of the cam projection or rib b on the shaft Bin such manner as to cause the rod or bar 0 and cross-head or plunger-block O to be acted upon by said cam. The rear swinging end of the rod or bar 0 is upheld by means of a jointed suspending-link, d cl, the lower part, d, of which passes through an eye or perforation in the bar and has a head on its lower end on which the bar O rests. The upper part, (1, which is connected through an eye in its lower end with a corresponding eye in the upper end of the part d, passes up through a perforation in an overhanging bar, D, secured to the upper face of and moving with the block 0, and has its end projecting above said bar D surrounded by a 0 spiral spring, d", clamped between said bar or a washer thereon, and an adjusting nut and washer, (1 on the upper end of the link or part d. The perforations in theplunger-rod Oand supporting-bar D, through which the parts of the suspending-link pass, are of sufficient diameter to allow the required vibration of the plunger-rod and the necessary movements of the parts of the link to accommodate such vibration. The bar D is rigidly secured to and moves wit-h the block 0, and its forward end projects and moves over the stationary bars A and A and has a slot formed in it near its forward end at 01*, through which an upright stop-pin, e, on a plunger, E, passes, as shown. The bar D has an upright flange, (P, at its forward end, through which a set-screw, d,

passes, in line with the pin 6, for regulating of its length,and preferably, where square,

is set with one of its angles downward and moves in a longitudinal perforation in bar A and in asocket in, bar A, of corresponding shape, for preventing any rotary movement of,

the plunger insaid perforation and socket. The forward end of the plunger E has a socket formed in it for the reception of the shank of the domino orits holder, hereinafter described, and the rear end hasja cylindrical shank, E, formed on it, which passes through a perforation of similar shape in the rear wall, a of the socket in bar A. This shank E is divided transversely, and a portion of it, E, is set in a socket at a in the forward face of block C in line with the shank E, and is secured in place in said block, so as to move with it, by means of a set-screw, 0".

A wedgeshaped slot is formed in the upper side of block 0, opening into the rear end of the socket c, and a wedge, 0, passes through said slot or opening into the socket c behind the shank portion E and is made adjustable up and down therein for setting the part E in or out and regulating the throw of the plunger E and the consequent amount ofstock to be upset, by means of a set-screw, 0 passing through the bar D and coupled to the upper end of the wedge in any suitable manner, and a jam-nut, c, which serves to prevent accidental'i'novement or displacement of the wedge 0*.

In front of the plunger E, and between the same and the forward frame, bar, or upright rib, A, upon a suitable support'therefor, are placed the several parts of the gripperjaws and die, which may be the form shown in Figs. 5 and 6, 7 and 8, or in the succeeding figures hereinafter explained, or of other form required, according to the work to be done.

The form of gripper-jaws and dies first used in upsetting the metal to form a knuckle-joint for carriage-bows is shown in the inner face view in Fig. 5,f indicating the fixed andf the movable part of the jaw and die. These parts are shown joined in rear elevation in Fig. 6, and the dominog, operating in connection therewith, is also shown in perspective and face views, Fig. 5. The square perforation f for. the reception of the square bar of metal to be operated upon, as also the die part f wherein the metal is upset to form the knucklejoint, is formed obliquely to the vertical sides of the die, as shown in Fig. 6, and the dividingline between the adjoining faces of the two parts thereof is at the upper and lower angles of the perforation and die, so that but a single angle of the bar projects within the face of either half of thejaw or die, a construction which greatly facilitates the clearance or withdrawal of the bar after it has been operated upon, as will be readily understood.

The bar of metal on which the knuckle is to be formed is inserted within the opening at the front end of the table A, and its heated end is projected within the die part thereof until it comes into contact with the end of the plunger bit or domino g, which is of a size and form to fill the opening into the die from the rear end thereof, and is secured, either directly or by means of a suitable holder, 9', (see Fig. 2,) in the forwardend of the plunger E. The dief has a concave face or shoulder at f, against which the metal is to be upset, and a shoulder atf forming a stopfor the domino g, and. the forward face of the latter is provided, also, with a concave end, g, into which the metal is forced in being upset to form the knuckle. The die thus formed is secured, one part, f, by a dovetail joint, to a frame or holder, H, adjustable laterally in suitable ways on the framc or table A, and the partfin a movable holder block, h, also made adjustable and adapted to slide in dovetail or T-shaped ways in a holder-frame, H. v p

The die f and holder H are adjusted laterally by means of a wedge, h, interposed between a side bar or rib, a, on the table and the holder, and a set-screw, h", for adjusting said wedge, and the die f and holder-block h are adjusted by similar means, except that they are set in a sliding frame, H, adapted to the jaw and die blockf toward or away fromthe block f for grasping and holdingor releasing the bar to be operated upon.

I is a tongue or flat bar secured at its rear endv to and. projecting forward from theblock or cross-head O, and moving in suitable ways in the frame or table A. The forward end of this tongue I is beveled or made wedgeshaped at t, adapting it to pass between the side of the holder-frame H and the supporting ledge or rib a of the frame, and thereby to crowd said frame and its jaw and diefinward toward the fixed jaw or die f for causing the said dies to firmly grasp the bar to be'operated upon and to hold said bar between them.

The block 0 and tongue I are. retracted by means of the cam-rib b, which acts on a notched bar, 0 projecting rearwardly from the block 0 and moving in suitable ways in the frame A, and the die-frame H and dief are retracted or thrown outward laterally for releasing the bar of metal (after it has been operated upon) by means of an upright arm, J, on a rockshaft, J, mounted in suitable hearings in the lower part of the frame A, and operated for the purpose stated by a stout spring, K, se

cured at one end to the frame A and having its opposite end connected by a link, 7a, with the arm J. The upper end of the arm J engages the frame H through a slot in its lower face or in other suitable manner.

Instead of the wedges h, for adjusting the dies in the holder frames, an eccentric, Z, (see Fig. 4,) may be interposed between the side bar of the frame and the die block or holder, and operated by means of a wrench or lever secured to the upper squared end, Z, of its pivot.

In Figs. 7 and 8 the grippingjaws and die are shown composed of four parts, m and m, representing the partsof the die correspond ing to the partsfand f of Figs. 5 and 6, and m M, two parts, forming an extension of the grippingjaws for grasping and holding the rounded or elliptical body of the rod, which has been previously brought into proper shape, by rolling or otherwise, after the first operation of upsetting to form the knuckle in dief f has been performed, and also after the slit or tongue of said joint has been formed.

The domino indicated at g is provided with a concave face or end similar to that shown in Fig. 5, but in addition thereto is provided with a central rounded tongue, g", matching the bifurcated portion of thejoint, and adapted to upset the metal thereof into proper shape for completing said part. \Vhere the other part of the joint is to be operated upon, the domino or plunger will be provided with two rounded tongues, arrangedat the sides thereof, for striding the central tongue of the knucklejoint.

N is a lever extending longitudinally above the frame and pivoted at n thereon, the forward end thereof being in convenient position to be grasped and operated by the attendant. The rear end is bent laterally and overhangs the plunger link rod or bar 0, and has a downwardly-projecting foot, N, which, when the forward end of the lever is raised, serves to depress the swinging end of the bar 0 sufficiently to cause it to be caught and operated upon by the cam rib orprojection b on the rotating shaft B for imparting a forward thrust to the block 0, plunger E, and wedge-arm I. In this operation, supposing the bar to be operated upon to be in position, the arm I is caused first to move the gripper-jaw and die f inward toward the fixed jaw f for causing said jaws to firmly grasp and hold the bar between them. The domino at the same time moves forward into the die and upsets the metal therein, after which the rib 1) acts on the bar 0 withdrawing the plunger, and the arm J moves the die f outward, thereby retracting thejawf and releasing the bar.

Fig. 9 represents an inner face view of onehalf of the die used in forming an angle in a carriage-iron; Fig. 10. a rear end view of said die and the holder-blocks, and Fig. 11 a perspective and front end view of the domino or plunger used in connection therewith. The die proper, as shown in these figures, is formed in pieces 19 p p 12 (two parts) and 12 19 the last two named serving to close the openingin the back of the parts 19 required for the in troduction and withdrawal of the upright part of the angle-iron. They are retained in position by means of springs g g, surrounding pins on the holder-blocks P P and engaging pins on the parts 19 and p, as shown.

is the domino or plunger, which passes through the opening at p, and which is operated to compress or upset the metal into the sharp angle shown in the die.

Fig. 12 shows one-halfof the die, and Fig. 13 the domino employed for forming the knuckleon the eudsofthe carriage-irons, which arejournaled on fixed pivots. (Indicated at r, Fig. 12.)

Fig. 14 shows an inner face view of one-half of. the die used to form the goose-neck; Fig. 15, first, an inner face view of one-half of the die for forming the collars on said irons; second, a front elevation of the rear portion of said die, and, third, a section through the latter, and Fig. 16, first, an inner face view of one-half of the die, and, second, a face view of the rear movable part thereof, for forming knobs or balls on said irons, whether for ornamental or other purposes.

Fig. 17 shows the form of the blank previous to being operated upon by the dies and domino, and Fig. 18 shows the form of the upset end of the blank.

Figs. 19 and 20 show, respectively, an angleiron and a straight iron having a ring or collar formed upon it by upsetting, as below described.

For forming the goose neck collars and knobs or balls referred to, the die is composed of four parts, two of which, as s and 8, being united to the sliding holder block or frame S, corresponding to h, by a dovetail joint, as shown in Figs. 15 and 16, and the other two being united to a fixed holder, S, corresponding to H. The parts 8" are adapted to slide longitudinally in the holder-block after they have been brought together to grasp and hold the iron to be operated upon between them, and so to upset'the metal between them and the fixed jaws 8 into the dies formed in their adjacent faces. This endwise movement of the parts 8" in one direction for upsetting the metal is effected by the forward movement of the plunger E, and the movement in the reverse direction by means of pins tand springs t, arranged within sockets formed in the rear faces of the parts 5, the pins acting against the adjoining faces of the parts 3 in a manner that will be readily understood.

By the construction of the machine and the use of various forms of interchangeable dies therein, as described, I am enabled to upset the metal at the various points required in carriage-top irons, and thereby to greatly facilitate and reduce the cost of manufacture of such irons as compared with the ordinary methods of making said irons.

Having now described myinvention, I claim as new 1. In a machine for upsetting metal in forming joints and other enlargements on carriagetop irons, a plunger, 0, having a forwardlyextending wedge-shaped tongue, I, for crowding a movable holdingdie, a cavity, 0, for the header-shank, a clamping-screw for holding said shank in said cavity, and a wedge, 0 provided with an adjusting screw, 0 for regulating the degree of insertion of the shank into the plunger-cavity, substantially as described.

2. The combination, with the plungerO and its lever N, having the angular foot N, of the plate D, mounted upon the upper side of the plunger and slotted and apertured to receive the holding and adjusting screws for the heading-die, the bar 0, hinged to the rear end-of the plunger, the double spring-sustained links located at the rear end of the plunger-plate and serving to sustain the bar 0, and the screw d, for regulating the throw of the header, substantially as set forth. 7

3. The holdingand upsettingdies,composed each of sections having an angular socket set obliquely to their line of union, and an upsetting-shoulder located within one section of said cavity, substantially as specified.

4. In a metal-upsetting machine, the dieholding frame H, in combination with awedge, h, provided with a holding screw, h, said wedge serving to adjust the die relative to the holding frame, substantially as described.

5. Thecombinatiomwiththe machine-frame, ofthe rock-shaft mounted in lower partthereof, and having the die-operating arm J, and the spring 70 and bar k, for operating said arm, substantially as set forth.

6. The combination, with the sectional holding and upsetting dies having an angular cavity set obliquely to the line of their union between their sections, and provided with an upsetting rib or shoulder in one of said sections, ofa domino having a recessed end and one or moretongnes set within said end,substantially as specified.

In testimony whereof I have hereunto set my hand this 7th day of January, A. D. 1886.
